SMART Helix Water

The SMART Helix Water is a powerful retractable sootblower with the focus on the selective cleaning of convective heating surfaces using water in boilers fired with waste, biomass and RDF.

Those types of boilers often have low steam parameters for the sootblowers.

Consequently the conventional steam sootblowers will not work effectively and the fouling will continue to increase, causing unplanned downtimes and reduced boiler availability.

Principle of cleaning

SMART Helix Water is a fully automatic cleaning system using water as the cleaning medium

It consists of a media supply unit with modules for the pump, for water inlet, water outlet and an automation unit

Two gear motors, one for the axial and one for the rotational movements, enables the cleaning system to precisely position the water jet in the gaps between the heat exchanger tubes and perform the cleaning

The novel water control allows an immediate build-up and interruption of the water jet for cleaning

This new cleaning method is called the 'Go-Stop-Clean-Go' technique

Travel range

Features

Only the deposit surfaces are hit by the water and this is solely done at the time of cleaning

Removal of complex deposits in convective heating surfaces without steam

Cleaning with water without thermal stresses on heat exchanger tubes ('Go-Stop-Clean-Go' model)

Instantaneous starting and stopping of the water jet for cleaning minimises the amount of water released into the boiler

Flue gas temperature remains in the rated range

Cleaning intensity can be adjusted to the actual deposit situation at any time
